Cytorrhysis

[1] Desiccation (relative water content of less than or equal to 10%) resulting in cellular collapse occurs when the ability of the plant cell to regulate turgor pressure is compromised by environmental stress.

[1] Unlike in plasmolysis (a phenomenon that does not occur in nature), the plasma membrane maintains its connections with the cell wall both during and after cellular collapse.

[3] Environmental stressors which can lead to occurrences of cytorrhysis in a natural setting include intense drought, freezing temperatures, and pathogens such as the rice blast fungus (Magnaporthe grisea).

[7] Production of sugars (predominantly sucrose), aldehyde dehydrogenases, heat shock factors, and other LEA proteins are upregulated after activation to further stabilize cellular structures and function.

[8] Photosynthesis is shut down to limit production of reactive oxygen species and then eventually all metabolic are drastically reduced, the cell effectively becoming dormant until rehydration.
